IMPROVEMENT IN CHAMBER-BUCKETS.

Specitication forming part of Letters Patent N0. 35,841, dated July 8, 1862.

`i`orm and'arrangement` of the offsets D D;

Fig. 2, a vertical section ofthe sa1ne,(when the cover is tted and secured in place,) through the line so x of Fig. l, showing the arrangement of the` handle G, spring nz, and cross-bar K, in connection with the iiangcd head ofthe vessel; Fig. 3, a vertical section of said vessel,

(with the cover off,)through`the line y y of Fig. 1, giving a side view of the stop N and notches 'n n in the offset of the flanged head; Fig. 4, an underneath View of the cover E of said vessel, showing the form and proportions of the cross-bar.

Similar letters indicate the saine parts in each' of the drawings.

It has been found necessary to obtain' va chamber-bucket which will afford an easy seat to an invalid, and which will admit of being easily and readily covered or uncovered, and yet be so closed by the cover as to prevent the escape of its contents in any form. My improved chamber bucket satisfies perfectly -these requirements.

as to leave the mouth of the vessel as open aspossible, and their relative proportions are about as represented in the drawings, Fig. 1. Upon this flanged annular head or rim B a metallic cover, E, Figs. 2 and 4, is made to iit closely and accurately by a water and gas tight beveled ground-in joint, e, Fig. 2, the beveled edge of the cover terminating in anarrow projecting flange, A, Figs. 2, 3, 4, which verse bar K is held closely against the sec? tional ribsL L on the under side of the cover, Fig. 4, at their point of intersection in the center by an india-rubber spring, m, which surrounds the shank F of the handle Gbetween the upper side of the Acover E and a shoulder on the said shank, Fig. 2.

The ribs L L are introduced in order to furnish a proper bearing for the transverse bar K on a plane even with the edge or'riin of the cover. This transverse bar K is of such a length that when the cover is placed upon the annular head B of the vessel the extremities of the bar may pass beneath the projecting plates or offsets D D. Stops N N, Figs. 2 and 3, project downward from the central portion of these offsets, and notches or depressions n n are formed on each side of the same in a rim or flange which increases in width from either end of the offsets to their central stops, N,

spring m, Fig. 2. The reaction of this spring will hold and secure the extremities of said bar when arrested by the stops N N firmly in the notches n n on either sido thereof, and

thus retain the cover tightly' upon the head of the vessel. The vessel being upon the floor, pressure is readily applied to the handle sufficient to overcome the resistance of the spring and allow the extremities of the bar K to be released from the notches n n on'the under side of the offsets D D and the cover to be easily lifted off.

A suitable handle, O, Fig. 3, is fastened to the side of the vessel, near the bottom of the same, at a point at a right angle with a line passing through the stops N N of the offsets D D to facilitate the removal of its contents.

The outwardly-curving flange C serves as a hold or handle to the vessel when the cover is off, and, in combination with the plates or ol sets D D, forms a comfortable seat to the vessel when used as a chamber-pot.

The vessel may be made of copper, tin, or other suitable material, and of any desirable size or shape.

`Having thus fully described my improved chamberbucket, what I claim therein as my invention, and desire to secure by Letters Patent, is-

Securing the coverE to the annular head or top B of the vessel by means of the handle G,

the CrossbarK, which is secured to thelower end of the shank F of said handle, the spring m, which embraces the said shank of the handle above the cover, and the offsets D D from opposite sides of the inner periphery of the saidringshaped top B of the vessel when the said parts are arranged and are made to op erate substantially in the manner and for the purpose herein set forth.
